Help Save My Grow, I'm Stumped!

[HappyJack420]

I currently have 4 plants in a small 2x2x4' grow tent, and all are going downhill fast! 2 are in their 95 day of veg and have been slow growing since I've sprouted them. Bagseeds.
The third plant is younger at 40 days of veg. Also a bagseed.
The smallest plant is a seedling 15 days old. It is an F2 Sativa cross.

I water when the soil is dry and inch deep, water with purified water (ph 7). Light schedule varies between 18 hrs light to 24 hrs, under a broad spec led 300 watt lamp with a fan blowing constantly.

The two largest plants have been slow growing the whole time they've been alive. Dark blue-green leaves, red stems, and the bottom leaves have been turning brown and crunchy/dying. One had yellow discoloration around the edges. I PH'd their runoff and found the soil had a ph of 5, so I replanted all 4.

They have now been replanted in Just Natural Organic potting soil last week, and I also flushed all but the smallest plant to get rid of excess N I believe was in the new soil. They showed signs of great improvement until a few days ago when they turned back to dark green. There is no new growth on ANY of them.

I smoke weed medicinally but I can't afford to pickup from shops anymore, and the quality is no where near suited for my needs. I need to produce my own. Please help!!

You need more aeration. You're suffering from potassium defficiency. Being caused by over nuting. Flush then feed 1/2 strength next feed.

I was told by someone I need to flush the plants again then apply an EWC and kelp meal slurry. Would that help the K deficiency? And if not should I add rice hulls or pearlite or... how can I improve aeration

Let dry then flush with water and bone meal, flush PH to 6.0. The bone meal will help her regain certain deficiencies that she can regain in her health.

I have a big bag of BLOOD meal at home, can I use that in place of the bone meal? And to clarify you say to flush with water that is 6.0 ph , with the additive mixed into it? Instead of flushing with plain water

Blood meal is high N and will burn your plants if not used properly, I would follow this advice, adding more wont always cure the problem.
Look a bit overwatered and high on N, wouldnt overthink or over flush it, 30% runoff would do for me.

Do not flush plants in organics. You will wash your beneficial microbes away along with available nutrients such as calcium. that will make your problem worse. A kelp meal foliar spray will get you going in the right direction. Blood meal is extremely hot. I don't use it. I wouldn't have advised a flush had I known you were running organic. Sorry.

In organics we use a carbon source to slow the movement of nitrogen. I had the exact same problem as you. Leadsled worked with me and I found out I was way low in minerals. Gypsum is great as it won't affect pH while soaking some of that N up.

Also understand the importance of kelp if you're not feeding fulvic acid on it's own. There isn't enough humic acid nor will there ever be to chelate enough minerals to meet your needs. A weekly kelp meal tea and a kelp meal top dress once a month are crucial.

I cheat and feed Neptune harvest liquid kelp fertilizer.

Your ph is too high.

No worries on advising a flush; I had already flushed the plants sometime last week, and about 3-4 days ago they started to go into great distress. So I already fucked up there...oops. When I transplanted I dusted each root ball with Azos from Xtreme Gardening and added their Mykos to the soil. So I probably washed that all away rite? Should I try and water with Azos?

Also I'm just a tad bit confused on what to do now. I can't tell if this new soil is still hot, or if I need an N buffer like you talked about, or an EWC and kelp meal slurry, or just a kelp meal foliar spray. I watered with plain water yesterday because the plants were wilted. More leaves have died and turned brown and crunchy.

Your ph is too high.

I disagree, only because everywhere I've looked has said soil ph is best in the 6.0-6.8 range. When I had ph'd the neutral water in the past down to about a 6.5, it caused my soil to turn extremely acidic. The runoff would read at a ph of 5!

 

[1diesel1]

Ph ing your nutes for soil grow should be at 6.0 on the money. Also ph ing your flush is a necessity if you are yousing a flushing agent that also should be at 6.0. I recently ran one coco with all my soil plants. I had originally planted in soil when transplanted from 10 g pots to 30 g pots with coco around the rootball. I kept the ph at 6.0 through late veg and into flower. She did well until week 3 of flower then started to show nute deficiencies. So I bumped her ph down to 5.5. She bounced rite back in a week.

Maybe tge meter is off

Here's what I did...i made a super duper compost. I make my own biochar. I had some charging. I mix half compost half hardwood lump charcoal that I took a sledge hammer to and let it sit in a grain bag in my shed for 2 weeks.

I mixed this up with basalt and glacial rock dust along with some gypsum and watered it in with fulvic acid and turned them 180 degrees.

Throwing down shredded hardwood mulch will absorb nitrogen too.
